SLED-RUNNER.

Specification of Letters Patent.

Patented April 2, 1907.

Application filed June 7, 1906. Serial No. 320,492.

To all whom, it nuty concern:

Be it known that I, FRANK BRYER, a citizen of the United States ofAmerica, and a resident of Waterloo, Blackhawk county, Iowa, haveinvented certain new and useful Improvements in Sled-Runners,'of whichthe following is a specification.

My invention relates to sled-runners; and the object of my improvementis to provide proper means for attaching a light runner to avehicle-wheel so arranged as to be easily put on or off at will.

This object I have accomplished by the means which are hereinafterdescribed and claimed and which are illustrated in the accompanyingdrawings, in which Figure 1 is a side elevation of my improvedsled-runner as attached to the wheel of a vehicle in correct operativeposition. Fig. 2 is a full-size cross-section of the fastening means,taken on the line a: a: in Fig. 1; and Fig. 3 is a full-sizecross-section of the runner, taken on the line y y in Fig. 1.

Similar reference-numerals refer to similar parts throughout the severalviews.

1 represents a wheel rotatably mounted on the axle 20 of any descriptionof vehicle, as usual.

I have shown in Fig. 1 a sled-runner composed of a tread 7, having avertical web 8, said web being single at the curved forward portion, butbifurcated at the bend to form a double web 6, extending to the heel ofthe runner.

At a point vertically below the axle 20 each of the webs 6 are extendedupward to form two parallel vertical uprights 5. The space between saiduprights 5 is made sufficient to permit the introduction thereinto ofthe felly and tire 18; but said space is contracted at its lower part toform shelves upon which the tire 18 may bear. If desired, the tread 7may be filled in solid below the tire; but, as shown in Fig. 2, I haveleft a space below said tire of sufficient width to accommodate asemicircular rubber tire, as indicated by the dotted lines therein.

17 represents a compression-collar whose under surface is curved to fitover the inner surface of the folly 1, while the upper surface of saidcollar is provided with a recess to fit over the hemispherical boss 19on the end of the thumb-screw 2. The thread of the thumb-screw 2 isarranged to work within a threaded opening in the cross-piece 8, the

latter having elliptical ends, whose major diameter is vertical, asshown in Fig. 1. These elliptical ends of the cross-bar 3 are so formedfor the purpose of being introduced into the elliptical openings 4 inthe uprights 5, said openings having their major axes in a horizontaldirection. The ends of the crossbar 3 are turned so as to have theirmajor axes coincide with the major axes of the openings 4 when it isdesired to introduce the ends of the cross-bar into said openings, andthen the cross-bar is turned about through an arc of ninety degrees,which causes the upper edge of said ends to overlap the upper edge ofsaid opening.

9 represents a horizontal connecting-rod, having a longitudinal slot 10to insure lightness, the forward end of said rod being pivoted on a bolt11 to the upper forward end of the sled-runner S. The rear end of saidrod 9 is provided with forks 12, extending horizontally in the directionof the axle 20. ithin these forks 12 is installed a fastening deviceidentical in form and function with that shown as placed within theuprights 5. Said fastening means are composed of a cross-bar 14, havingits elliptical ends similarly set within the elliptical openings 15 ofthe forks 12 and provided with a thumb-screw 13 and compression-collar(not shown) to hold and compress the felly 1 tightly against the innerface of said fork 12. It will thus be seen that when both sets offastenings have been firmly set against the inner surface of the felliesof said wheel a strong truss connection is formed thereby through themedium of the intermediate part of the wheel, which is incapable ofdisplacement by reason of any ordinary shock.

It will be obvious that this improved form of sled-runner can be easilyattached to any wheel by simply removing the thumb-screws andcross-bars, inserting the fellies into the forks of the connecting-rodand the uprights of the runner, replacing the cross-bars in the mannerheretofore described, and then inserting and screwing down tightly thethumbscrews. The connecting-rod and runners may be removed from'thevehicle by reversing this operation.

As my improved sled-runners are so light and compact in arrangement,they may be stored with little loss of room or carried to and fro 011the vehicle itself in order to be made use of in any emergency.
